Abstract: A motor (3) drives the pump (8) of a torque converter (7), the turbine (11) of which is connected to the crown (16) of a planetary gear train (13), the satellite carrier (18) of which is connected to the output of the transmission.      The pump (8) is connected to the planet wheel (14) of the planetary gear train (13). The crown (16) is mounted on a free wheel (22) preventing rotation in the backward direction. During starting, the power passes via the planet wheel (14) into the gear train (13) which behaves as a mechanical reducer with the crown (16) immobilised by the free wheel (22). Then, the torque transmitted by the converter to the crown (16) exceeds the reaction torque strictly necessary, and the speed of the crown (16) becomes progressively equal to that of the planet wheel (14). The gear train (13) operates as an adder of the powers received mechanically at the planet wheel (14) and hydraulically at the crown (16). An automatic direct drive (23) is provided.      The invention is used for minimising the control, the losses in the converter, the weight, cost and bulk.

Title: Medium Consistency Pulp Ozone Bleaching
Inventor: PHILLIPS JOSEPH R
IPC: D21C9/153
Filed: 1991-12-13
Granted: 1996-08-06
Abstract: Medium consistency (e.g. about 6-15%) paper pulp (from 38) is effectively bleached with ozone (from 16) in a carrier gas (typically oxygen) by effecting efficient separation of carrier gas from the pulp after reaction with the ozone, and introducing the ozone into the pulp at a pressure of about 10-13 bar. Ozone in oxygen and medium consistency paper pulp are fed to a fluidizing mixer (12); the intimate uniform mixture produced is then passed upwardly in a reaction vessel (17) until about 99% of the ozone has been consumed, and then separation of gas from the pulp is initiated by moving the pulp mixture into a generally horizontal tube (21) leading to a gas zone in a large diameter retention vessel (22). A pressurized gas pad (26) is maintained at and above the introduction of the pulp into the retention vessel, while the level (29) of pulp in the retention vessel is maintained below the point of introduction. The pulp may be withdrawn from the retention vessel with a fluidizing degassing pump (32), and the pressurized gas removed from the top of the vessel (through 35) may be fed to an apparatus (61) using oxygen gas under pressure. <IMAGE>   <IMAGE>

Title: Potassium fertilizer from aluminum reclamation by-products
Inventor: STAUFFER WILLIAM O
IPC: C05D9/02
Filed: 1992-07-22
Granted: 1996-07-16
Abstract: Scrap aluminum is reclaimed by a salt flux-based reclamation process using potassium chloride in place of the commonly used sodium chloride. The spent flux which remains after the recovery of the aluminum is useful as a soil fertilizer, with the potassium content of the flux serving as a source of potassium nutrient for the soil.  The potassium in the spent flux is highly water soluble at all values of pH while the aluminum in the spent flux remains at a limited solubility, particularly under the conditions expected to be encountered in soil.  Thus, despite the known phytotoxicity of aluminum and the presence of aluminum in the spent flux, the spent flux is discovered to be useful as a plant fertilizer with the maximum benefit from the potassium and minimal if any harm from the aluminum.

Title: Implantable cardiac function monitor and stimulator for diagnosis and therapy delivery
Inventor: SALO RODNEY W
IPC: A61N1/362
Filed: 1992-11-03
Granted: 2001-03-20
Abstract: An implantable monitor/stimulator is disclosed that monitors and assesses indices of cardiac function, including the strength and timing of cardiac contraction, then automatically executes a physician-selected mode of therapy. It accomplishes this by assessing impedance, electrocardiogram, and/or pressure measurements, then calculating various cardiac parameters. The results of these calculations may be stored within the device, telemetered to an external monitor or display and/or may be used by the physician to determine the mode of therapy to be chosen. If indicated, therapy is administered by the device itself or by telemetering control signals to various peripheral devices for the purpose of enhancing either contraction or relaxation of the heart.      The cardiac parameters that are calculated all provide an assessment of level of cardiac function by monitoring changes in ventricular filling and ejection or by calculating isovolumic phase indices of heart contraction. Examples of such parameters are ejection fraction, cardiac output, stroke work, and/or various pressure-volume relationships. These parameters determine the mode of therapy that will be selected by a physician. Choices of therapy include several forms of pacing of cardiac or skeletal muscle, and telemetry to implanted or external units for drug infusion or for monitoring by a central data system.

Title: Method of controlling the flow of cells
Inventor: BOYER PIERRE
IPC: H04L12/56
Filed: 1993-01-12
Granted: 1999-07-27
Abstract: There is assigned to each virtual circuit a period (pm) corresponding to the theoretical minimum period between two consecutive  cells of the virtual circuit and a maximum time limit (dm).  The imaginary time of emission on the output multiplex of the last cell belonging to each virtual circuit is stored, and, upon the arrival of a new cell of a virtual circuit, a threshold time calculated by adding its actual time of arrival and the maximum time limit is compared with the imaginary time of emission expected of the new cell in the course of being processed, the time being calculated by adding the imaginary time of emission of the last cell emitted and the minimum period (pm).  If the result of this comparison shows that the threshold time is earlier than the imaginary time of emission expected (tde + pm), the incoming cell is not re-emitted, whilst, if it shows that the threshold time is later than the imaginary time of emission expected (tde + pm), it is emitted on the output multiplex, the imaginary time of emission of the incoming cell then being calculated, then stored in relation to the virtual circuit to which the incoming cell belongs.

Granted: 2005-03-29
Abstract: A device for heat shrinking thin film onto open-topped containers to form spill-resistant covers is shown.      A radiant energy source is intermittently energized in association with timers to direct radiant energy towards the thin film. An energy absorbing body is associated with the thin film to absorb energy and create heat adjacent to the film which in turn causes the thin film to shrink. The energy absorbing body can be the adaptation of the thin film to be opaque to the radiant energy by either being coated with an energy absorbing coating such as printing, or being made partially opaque by means of tinting. The container can also be adapted to absorb energy by including a darkened band adjacent the upper edge of the rim. The device can also interpose an energy absorbing body, such as a darkened aluminum screen adjacent to the film to be heated to cause the thin film to shrink. The device shrinks the thin film around the rim first, then shrinks the film across the top of the container to form a spill-resistant cover. In one embodiment, printed patterns on the film can be used to create perforations.
